is 175 cfm for an inline fan enough for a 20 x 36 x 63 inch tent? this shit racks my brain i use metrics.
Assuming it's a real inline fan, and not a "duct booster" type.
20/12= 1.66 Feet
36/12= 3 feet
63/12= 5.25 feet
1.66x3x5.25= 26.14 Cubic feet
In order to cool and ventilate you'll want a 6" 440cfm exhaust fan.
Can you explain the relation between the actual volume and why i need 440 cfm for 26.14?
Not trolling i actually dont knowif 26.14 goes into 440 16 times doesnt that mean 16 room changes per minute? that seems a bit much... whereas the 175 would only be 6 a minute.
Not trying to overkill it here i dont even think my tent will hold something bigger than 6 inch
Another factor not everyone always asks is outside cab temp....I am cooling about the same size cab with an 80 cfm bathroom fan right now...no filter....around 250 watts.....my outside temp is low to mid 60s....inside the plants sit at a comfy 79
4" duct
